Building a Dead Silent PC

Posted by michael on from the i-still-have-the-scar dept.

Jouster writes "The folks over at HardCoreWare.net have finally lost it. They built a PC that's well over twenty times quieter than their comparison PC (40 dB versus 65). And it's no sluggard, either: P4 2.80 GHz, 7200 RPM hard drive and--get this!--an overclocked to the max GeForce4 Ti 4200! The only fan in the entire system is in the PSU."

  1. I have to wonder...... by idiotnot · · Score: 5, Interesting

    exactly what this will do to component life. As you can see from the graphs they posted, the CPU and graphics card do run noticably hotter than with the stock cooling.

    To me, the small amount of noise created by a the stock CPU fan and graphics card cooler are worth the bit of extra noise.

    A very quiet case fan might be a good addition to this to help draw heat out of the case. That big plastic window doesn't help add anything to radiational cooling from the case, either.

    And my athlon isn't *that* noisy, especially when it's tucked away underneat the desk.

    I think it's great that these guys did this, and I'm quite impressed at the hardware statistics and performance for such a quiet system. Although, there is a conspicuous lack of one element from the whole article...

    Longevity.

    While I've been desperately wanting a completely quiet computer that runs decently for some time now, I don't have the money to invest in a solution that is going to last only for a year or so. I guess I wish these guys had done more extended testing of their system.

    Has any other /.er made a comparable system? How has it lasted?

    Maybe I'm just a skeptic, but an overclocked GeForce 4 Ti with no active cooling makes me anxious, and somewhat hesitant.

      My solution to making my PC quite was very simple: I built a big-ass sound-insulating box for it. The box itself is made of particle board, lined with acoustic ceiling tile and carpet. I cut fan holes in the side of my original case, and mounted three fans to blow directly onto the CPU, memory and graphic board.

      The fans on the side of my case pull in air from a 20" long carpet-lined duct--it acts a lot like a car muffler. The air moves through, but the carpet absorbs nearly all the sound (the sound needs to make two 90 degree turns to escape the air channel). There is a similar duct in the back of the case for outgoing air.

      My 'new' case has more airflow than the computer originally had, so my internal temps are only a little higher than they used to be. I built the box with a weekend and ~$25. Now I can leave my computer on all the time without making my ears ring. If you've got access to a wood shop, it's a very effective way to make a quiet PC.

  3. Most Apple products have been silent. by Anonymous Coward · · Score: 5, Interesting

    Most Apple products have been silent.

    Its one of the main reasons people like to buy them.

    Even some of the G4s (cube) keep the fan off unless critical.

    powerbooks are similarlysilent unless emergency fans kick in.

    The balance of other modesl, such as imac are designed with columnar "chimney effect" air flow out the tops.

    And many famous apples have no fan at all whatsoever, not even on powersupply : Apple II, IIe, IIc, IIgs

    Many musicians like the newer macs with sampler gear because they don't have to worry about systyem sound so much.

    External D/A in usb allows noise free amplification far from motherboard on most all mac models in last 3.5 years.

    Mac lovers hate noise it sems.

    I wish dual cpu AMDs could be made much quieter.

  4. I can think of one idea to get even cooler by Navaash+Fenwylde · · Score: 5, Interesting
    Those are some gigantic heatsinks. The processor heatsink alone is frigheting enough. But there does seem to be one solution that can be even quieter and can cool both Pentiums AND Athlons...

    Water cooling!

    It's certainly different, using water to carry off and circulate the heat. Obviously, it requires a large degree of trust, as one leak can short out your entire system in a heartbeat. I've been around these beasts, and they certainly seem quiet enough.

    I imagine they would be great for overclockers :D

  5. Old news by Maniakes · · Score: 5, Interesting

    The PowerMac G4 cube (bottom of page 4, "Noise characteristics") was only 31 dB. That's 2,512 times quiter than this "silent" PC.
